The file needs proof of citizenship, an employer letter setting out the professional duties, the period sought and the arrangements for payment, and the credential itself. A degree from outside Canada is acceptable, but it usually needs a credential evaluation showing United States equivalence, and every document not in English requires a complete certified translation.
A foreign parchment needs a translator and an evaluator
Nothing in the rules requires a Canadian degree. What the rules require is that the applicant meets the listed profession's standard, and an officer at a port of entry has minutes rather than hours to reach that conclusion. Two documents do most of the work.
A credential evaluation from a recognised service states what the foreign qualification is equivalent to in United States terms, and a certified translation renders the parchment and transcript in full, with the translator's attestation of competence and completeness attached. Partial translations and informal ones are a common cause of a wasted trip. Hypothetical example: a horticulturist now living in Sainte-Cécile-de-Milton holds a baccalaureate from a university in Tunisia and manages propagation for a local tree nursery.
Her citizenship certificate answers nationality, but the degree needs both an evaluation and a full translation of the transcript before the Horticulturist entry can be shown to be satisfied.
